Why DosUmbLink() tries to join free blocks (in low memory) when uppermem_link switched from 1 to 0 (but not when it switched to 1)? I think, this is wrong: blocks joining should be performed (by RBIL) only for memory allocation in DosMemAlloc() and DosMemChange() (realloc).
James, this is a question for you since you added initial UMB support -- memmgr.c of kernel 2021 does the same thing, so I have no idea why...

I can't remember that far back. I thought this hack was removed? Any ways~ I think it was behavior I observed with M$dos. It joined high and low memory by assigning a memory block to the end of low mem which linked the video/bios memory in the chain with high memory. I do not have the code here with me ATM. Is Uppermem_link a flag I used during config.sys batching to set the run state with processing of UMB's? I think it is a state switch. At the time I added the code it was a hack. Sorry for not being so helpful, 8^( James
